As you look at the stretch blow molding process as a whole, you see even more advantages. At the top of the list is the fact this innovative molding method stretches plastic bottles, jars, and containers in both the hoop and axel direction. Known as biaxial stretching, this increases tolerable drop impact, tensile strength, barrier properties, top load, and clarity.

According to experts who rely on a PET stretch blow molding machine daily, the increased strength makes it possible for manufacturers to reduce the overall weight of the finished product by as much as 15 percent. That has a significant impact on the cost of production, as well as shipping.

Whether you need plastic bottles, jars, or containers for water, milk, juice, laundry detergent, shampoo, and conditioner, or something entirely different, both the single- and two-stage stage stretch blow molding machine is critical to your success. The goal is to purchase machinery from a trusted source, one with years of experience in these machines and that offers variety and affordability.
